RE-ANALYSIS OF INTERNAL PERMANENT MAGNET BRUSHLESS DC MOTOR WITH INCREASED MAGNET DIMENSIONS

Abstract

Brushless DC (BLDC) Motors have started to attract great attention and use in the industry in recent years due to their high efficiency and speed. Compared to other machines used in the industry, these motors have made these motors more attractive than other motors due to their features such as high output power and efficiency, high reliability, less weight and being usable for high speed applications. Although machine design procedures exist as a combination of many different sources, the need for a step-by-step design procedure from the electromagnetic side is an absolute necessity. In this study, it is aimed to design and analyze Internal Permanent Magnet Brushless DC (IPMBLDC) Motor by using ANSYS-RmExpert-Maxwell integrated structure that performs a solution based on Finite Element Method (FEM). After determining which materials will be used for the stator and rotor for the design and what dimensions these materials should be, all other parameters of the machine are determined and defined. The design was improved by using the general radial flux concept in the study. In addition, RMxprt, an ANSYS software tool, was used to create the geometry of the engine and calculate the basic design parameters. Later, this design was transferred to Maxwell 2D environment to perform electromagnetic field analysis of the motor. When the results of the analysis were compared with the results in the literature, it was concluded that the results were satisfactory and the efficiency was high
